TD62S310AFM TOSHIBA Bipolar Digital Integrated Circuit Silicon Monolithic TD62S310AFM 1-Channel Darlington Source-Current Driver The TD62S310AFM is a 1-channel noninverting source-current driver. The driver incorporates an input resistor which limits output pull-down resistance and base current. The driver is optimal for driving fluorescent display tubes and LEDs. When using the driver, pay attention to the thermal conditions. Features · Ultra-small HSON6 package with heat sink on rear · Large output voltage: VOUT = −50 V (min) · Large output current: IOUT = −100 mA (max) · Built-in input resistor: RIN = 10 kΩ · Input signal: High Level Active Basic Circuit Diagram INPUT TEST 2 5 P-GND VCC 3 4 NC VCC INPUT 10 kW Rpd 6 10 k9 1 20 k9 OUTPUT 2.6 k9 Pin Connection (top view) Weight: 0.017 g (typ.) TEST OUTPUT P-GND Note 1: Diodes shown using dotted lines are parasitic. Do not use them. Note 2: When using the driver, connect the OUTPUT pin to the TEST pin. Note 3: When using the driver, connect the P-GND pin to the heat sink on the rear of the package. 1 2001-12-05 TD62S310AFM Maximum Ratings (Ta = 25°C) Characteristics Symbol Rating Unit Supply voltage VCC -0.5~50 V Output voltage VOUT -50 V Collector-emitter voltage VCEO 50 V Output current IOUT -100 mA Input voltage VIN -0.5~15 V PD (Note 4) 0.78 W Rth (j-a) (Note 4) 160 Power dissipation °C/W Saturated thermal resistance Rth (j-c) (Note 5) 25 Operating temperature Topr -40~85 °C Storage temperature Tstg -55~150 °C Note 4: 114.3 ´ 76.2 ´ 1.6 mm glass epoxy film substrate Cu heat dissipation pattern 100 mm 2 Note 5: When an infinite heat sink is mounted.

Caution on Application 1. The device does not include protectors such as an overcurrent protector and an overvoltage protector. Applying excessive current or voltage may damage the device. Thus, design with great care to prevent excessive current or voltage from being applied to the device. The device may also be damaged by short-circuits between outputs and power supply/ground. Take care when designing output, VCC and GND line. 2. If the TD62S310AFM is used to drive an inductive load (such as a motor, solenoid, or relay), Toshiba recommends that the diodes be connected between pin 1 and pin 5 so as to absorb the counter electromotive force generated by the load. Please adhere to the maximum ratings of this device. 3. Be sure to mount the device in the correct orientation. Make sure that the positive and negative power supply pins are connected the right way round. Otherwise, the absolute maximum current and power dissipation ratings may be exceeded and the device may break down or undergo performance degradation, causing it to catch fire or explode, and resulting in injury. 3 2001-12-05 TD62S310AFM Package Dimensions Weight: 0.017 g (typ.) 4 2001-12-05 TD62S310AFM Preliminary land pattern 0.7 1.3 0.7 1.6 0.25 0.7 1.6 0.6 2.2 0.6 Unit : mm Preliminary PCB trace dimension 5 mm 10 mm 5 2001-12-05 TD62S310AFM RESTRICTIONS ON PRODUCT USE 000707EBA · TOSHIBA is continually working to improve the quality and reliability of its products.
